"Feeling the touch of a mechanical keyboard and hearing those keys is a delight. And the best part is that I can switch it from one to the other just by changing the Bluetooth settings on the computer. If you were ever a fan or curious about Mechanical Keyboard - give it a try, Cosari has great return policy if it is not your style - but I bet once you try it, you will never want to go back."
Mark W.
"Creamiest-sounding keyboard ever! To be very honest, I have been looking for a nice keyboard that carries the 'creamy' sound for a while, and this is it! The switches and keys feel so incredibly smooth and not loose at all. The fact that it is pre-lubed made it much easier as I didn't need to do that myself (needs strict care). For the price, you absolutely get what you're looking for!"
Manish T.
"SUPER NICE! Love this keyboard. The keys come pre-lubed and are super creamy! It feels wonderful to type on. It’s also easy to customize! It has a program you can download to change colors and key binds too. Super super useful. The white is a little more offwhite or eggshell like, but still pretty white! Very nice keyboard."

Good quality and great sound
"For the price, this keyboard is absolutely exceptional. It is creamy right out of the box. The keys are bouncy and responsive. The little screen is so cute and can play a gif image on it. Battery life is good but not great. Lighting is bright but can be dimmed to conserve battery if needed with several lighting patterns. If you want a nice keyboard straight out of the box, look no further."

Keys are very creamy sounding
"This is my first time using a 75% keyboard and there was somewhat of a learning curve but it was effort well spent. The keys are soft to the touch but still provide a well needed response to make a seamless transition possible typing and traveling between the keys. I see myself using this for sometime and at the price point it is set at, I believe this item is worth it."

Get it before the manufacturer realizes what they have.
"Perfect ergonimic minimalist keyboard... perfect clicking sound, just the right amount of back lighting RGB if your set up doesnt need to go crazy. But if it does, those options are for you too. This keyboard is amazingly priced, get it now before they realize what they have!"

The greatest and most affordable keyboard!
"WOW this was a good purchase. They come with pre-lubed switches, which sound so nice in person. It sounds like bubbles popping, which was not something I was expected straight out of the box, and the size was perfect for me and my desk space. Even my friends ended up buying one because of how cheap and convenient it is! Save your money and buy this extremely accessible and nice sounding prebuilt keyboard!"

Smooth like butter.
"Love the blue and white aesthetics. Nice as hell to type on. Also because there is no screen on keyboard where the placements of the keys are, you're less likely to use the wrong keys while typing. Feels creamy and smooth like buttermilk. I think I can fall asleep just from typing on this keyboard. Chef's kiss to this keyboard."

New to mechanical keyboards
"This was my first mechanical keyboard and I love it. Changing the key caps was easy and the switches that it comes with are great. Lots of customization options and I love the knob that adjusts brightness! Have only used the USB connection so far and have not experienced any lag. Battery life seems good but I also don’t keep the backlights on all the time."

Meet Our Expert,
Creator of “Cosari”
When I set out to create the Cosari Gaming Keyboard, I wanted to deliver more than just another gaming peripheral—I wanted to give gamers a tool that amplifies their skill and enhances their experience. As a lifelong gamer, I’ve spent countless hours battling latency issues, dealing with worn-out keycaps, and wishing for a keyboard that felt as good as it performed. That’s why I crafted Cosari, combining precision-engineered hot-swappable switches, vibrant RGB lighting, and a durable, ergonomic 75% layout. It’s built for players who demand reliability, customization, and comfort, whether they’re grinding ranked matches or creating content. With Cosari, my goal was simple: to create a keyboard that adapts to you, so you can focus on dominating the game.
